An interface to support model component of the Struts2 MVC architecture.

An interface to support model component of the Struts2 MVC architecture. This interface should implement action classes which applying a user model as a generic parameter. If an action class implements the interface ModelDriven then it needs to return an object from the getModel() method. Struts2 will then populate the fields of this object with the request parameters, and this object will be placed on top of the valueStack once the action is executed. Validation will also be performed on this model object, instead of the action.

ModelDriven action uses it's own interceptor modelDriven which included in the defaultStack interceptor stack. Thus every action that uses that stack invokes this interceptor to check if an action is instance of ModelDriven then applying a model to it.

There's also a ScopedModelDriven interface that is used for models that has lifecycle for the specified scope.
